ActiveMQ Maven插件配置

Question

I have a problem with using ActiveMQ in a Spring project. I am trying to integrate the ActiveMQ maven plugin into my project to use it in integration tests. Here my configuration:

The problem I have is using the jetty Namespace. The schema cannot be found and downloaded: http://jetty.mortbay.org/jetty.xsd Here a link from Apache ActiveMQ: http://activemq.apache.org/complex-single-broker-configuration-stomp-only.html

There is not specified any location for this schema. The ActiveMQ starts without having the schema location but if I use a schema validator like in Eclipse it tells me that I have an error in the file and the schema location cannot be found.

Any idea where I can find the schema for the jetty element ?

Answer 1

I ran into this problem too and I lost a whole hour to find a solution.

Essentially the example in the documentation is outdated.

The dependencies required to enable jetty with activemq-maven-plugin are as follows:

 <dependency>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-xbean</artifactId>
    <version>6.1.25</version>
    <exclusions>
        <exclusion>
             <groupId>org.springframework</groupId>
             <artifactId>spring</artifactId>
        </exclusion>
    </exclusions>
 </dependency>
 <dependency>
    <groupId>org.eclipse.jetty.aggregate</groupId>
    <artifactId>jetty-all-server</artifactId>
    <version>7.6.7.v20120910</version>
</dependency>

Following is the complete configuration of the activemq-maven-plugin:

<plugin>
    <groupId>org.apache.activemq.tooling</groupId>
    <artifactId>activemq-maven-plugin</artifactId>
    <version>5.8.0</version>
    <configuration>
        <configUri>${configUri}</configUri>
        <fork>false</fork>
        <systemProperties>
            <property>
                <name>javax.net.ssl.keyStorePassword</name>
                <value>password</value>
            </property>
            <property>
                <name>org.apache.activemq.default.directory.prefix</name>
                <value>./target/</value>
            </property>
        </systemProperties>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-spring</artifactId>
            <version>5.8.0</version>
        </dependency>
        <dependency>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jetty-xbean</artifactId>
            <version>6.1.25</version>
            <exclusions>
                <exclusion>
                     <groupId>org.springframework</groupId>
                     <artifactId>spring</artifactId>
                </exclusion>
            </exclusions>
         </dependency>
         <dependency>
            <groupId>org.eclipse.jetty.aggregate</groupId>
            <artifactId>jetty-all-server</artifactId>
            <version>7.6.7.v20120910</version>
        </dependency>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-leveldb-store</artifactId>
            <version>5.8.0</version>
        </dependency>
    </dependencies>
    <executions>
        <execution>
            <id>start-activemq</id>
            <goals>
                <goal>run</goal>
            </goals>
            <phase>pre-integration-test</phase>
        </execution>
    </executions>
</plugin>

Then to enable jetty is enough to import the jetty configuration file into the activemq the configuration file.

The following snippet is taken from the file ${ACTIVEMQ_HOME}/conf/activemq.xml in the ActiveMQ latest release at the time of this writing (5.8.0):

<beans
          xmlns="http://www.springframework.org/schema/beans"
          xmlns:amq="http://activemq.apache.org/schema/core"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
          http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd">

    <!--
        The <broker> element is used to configure the ActiveMQ broker.
    -->
    <broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}">

       ...

    </broker>

    <!--
        Enable web consoles, REST and Ajax APIs and demos

        Take a look at ${ACTIVEMQ_HOME}/conf/jetty.xml for more details
    -->
    <import resource="jetty.xml"/>

</beans>

Cheers,
